## Summary Fix SHOW BACKENDS command output field order mismatch with BackendsTableValuedFunction.SCHEMA definition. ## Problem The output fields of SHOW BACKENDS command were not in the same order as the BackendsTableValuedFunction.SCHEMA definition, causing field values to be displayed in wrong columns: - CpuCores showed NodeRole value (mix) - Memory showed CpuCores value - NodeRole showed Memory value ## Solution 1. Reorder fields in BackendsProcDir.getBackendInfos() to match SCHEMA: - CpuCores -> Memory -> LiveSince -> RunningTasks -> NodeRole 2. Synchronize the same fix in MetadataGenerator.backendsMetadataResult() 3. Add unit test to verify field order ## Test - Unit test added in BackendsProcDirTest.testBackendInfoFieldOrder()
